MOLDING-MACHINE.

Speeification of Letters Patent.

Patented Feb. 6, 1906,

Application filed May 20,1905. Serial No. 261,472.

Be it known that I, J OHN Roenns, a citizen of the United States,residing-at Platteville,

, in the county of Grant and State of Wisconsin, have invented a new anduseful Molding-1 Machine, of which the following is a specification. 7

This invention relates to means for manu- 1 facturing articles ofconcrete or cementitious material, and more particularly fence-posts,

- though not necessarily limited to the latter.

One of the principal objects is to provide a novel and simple machine ofthe above character, whereby posts or other articles may be rapidly andinexpensively manufactured and will be without blow-holes or othermaterial defects. To this end novel mechanism is provided for thoroughlymixing the material in a dry state,.moistening and simultan'eouslystirring the mixture to thoroughl eliminate the air and gases, andthere: after eeding the same into successive molds, which areautomatically shaken and joggled to drivefrom the concrete the remaininggas and also the surplus water, thus causing the material to becompacted thoroughly in the molds and as a result forming articles thatare free from defects. An embodiment of they invention that isconsidered preferable is illustrated in the accompanying drawings and isdescribed in the following specification. An inspection of the claimswill show, however, that the invention is not limited to the exactstructure set forth.

In the drawings, Figure 1 is an end elevation of the machine. Fig. 2 isa sectional view on the line 2 2 of Fig. 1. Fig. 3 is a -cross-sectionalview.- Fig. 4 is a plan view of the measuring device. Fig. 5 is a topplan view of the mixing mechanism. Fig. 6 is a plan view of a portion ofthe mold-carrier. Fig. 7 is a'detail view of the operating means for themold-shaking mechanism.

Similar reference-numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated a suitable frame 8 is employed,.in whichis journaled the upright shaft 9 of a rotatable carrier having ahub-plate 10, onwhich are pivotally mounted a plurality of radiallmold-supporting arms 11, movab e in a vertical direction. Thesemold-supporting arms are pivoted at their inner en s to and be; tweenguide-flanges 12, their outer ends pro-'- jecting beyond the hub-plate10 and carrying disposed cupped holders 13, in which the lower ends ofthe molds 14 are seated. The said molds 14 in the present instance arein the form of openended tapering tubes, the smaller ends beingsupported upon the cups 13, the upper portions being slidably mounted ineyes 15, canried by the outer ends of guide-rods 16, se

cured to the upper portion of the shaft 9.

Suitably supported in the frame Sabove the-carrier at one side of theaxis of, rotation thereof is a hopper 17, having a dependingdelivery-spout 18 disposed above the path of movement of the upper endsof the molds 14.

This spout is controlled by a sli ing gate 19,.

movable transversely beneath the same and operated by a lever 20,connected to said gate by a link 21. In the hopper 1'] are locatedmixing or stirring devices comprisingplows or shovels 22, carried byarms 23,'that are secured to an upright shaft 24, arrangedconcentrically with respect to the hopper; The shaft 24" in the presentinstance 1s operated from a driving-shaft 25, through the medium ofintermeshing beveled gears 26.

Secured to the shaft 24 above the hop e1 17 is a downwardly-inclinedconical sprea er table 27, of less diameter than the hopper, as clearlyshown in Fig. 2. Between the spreader-table 27 and the stirrer shovelsor plows and secured to the shaft 24 are radially-disposed vsprinkling-pipes 28, operating over the hopper and supplied from a pipe29, in. communication with the pipes 28 through a suitable coupling 30.

Located at one side of the frame 8 is measurin mechanism, comprising ahopper 31, divi ed by a partition 32 into compartments for gravel rotatethrough the lower portion of the hop per is a rotatable measuringdevice, com rismg radially-disposed walls 33, carried shaft 34 andforming pockets 35.

rice the material therefrom, as will be apparl his .measuring device, 0erating through the lower portlons of hot compartments,'carand cement,and journaled so as to cut, and delivers it to a downwardly-1nclinedchute or spout 36, that leads to the boot 37 of a suitable elevator- 38.The elevator 38 is located at one side of the frame and maybe-of ansuitable structure, inthe present instance eing shown a an endlessserieaof pockets 39, carried by a chain 40', 0 rating .over upper andlower pulleys 41.

he-lower pulley is carried b a shaft 42, rojecting from one side of theboot 37 and aving a sprocket'wheel 43, connected by means IIO of a chain44 with a sprocket-wheel 45 on the shaft 34. The upper pulley 41 ismounted on a shaft 46, projecting from one side of the casing of the eevator and having a sprocketwhee 47, driven by a chain 48,- which isengaged by a' s rocketwheel 49. on the drivingshaft 25. mm the upper ordelivery end of the elevator adownwardly-inclined trough or spout leadsto a oint above and at one side of. the spreader-ta le 27-.

F or the (purpose of shaking the molds while being fille anactuating-bar 51 is pivoted at its inner end, as shown at 52, beneaththe carrier and directly adjacent tothe lower end of the shaft 9. Thisbar orlever is provided between its ends with, a transversely-dis-,posed mold-support-enga'ging block 53, having a curved upper edge 5.4and'lo'cated beneath the path ofmovement of the outer ends of themold-supporting arms 11, being movable into said path, as herr..-inafter described. The bar 51 and-block 53 are, as illustratedin Fig. 3,disposed in the vertical plane of the spout 18, so that when'a mold,is

disposed beneath said spout the supporting.

arm for such mold is located over and in engagement-with the block 53,carried by the ar 51. The outer end of said bar 51 has an extensibleyieldi-n link connection 55 with one arm of a be -crank lever '56, uponthe-frame 8, the other arm of said lever having an antifriction-roller57 enga ed by av wiper'cam 58, carried 'by the drive aft 25. p

The saidlink 55 consists of sections the upper of which is connected tothe bell-crank 56, the lower being in the form of a boxing 59, in whichthe lower hinged arm of the upper section is slid ably mounted, saidboxing containin a spring'60, bearing against. the

upper en of the boxing and the lower end of the upper section, all ofwhich is illustrated in Fig. 1.. 3 I

In operation the gravelvand cement are introduced, respectively, intothe compartments of the measuring-hopper 31 and being deliveredtherefrom in proper proportion by the measu-ring'device Will gravitatedown the inclined chute 36 into the boot of the elevator. Said elevatorwill carry. the material upwardl. and deliver it u on the chute or spout50, W 'ch in turn wi 1 direct it upon the s reader-table. By the time ithasreached t 's table the material has been thoroughly comrningled and,gravitating down the table, will enter the outer portion of the hopper.In this ho' per it is thoroughly stirred and mixed by t e shovels orplows, and at the same g time water is allowed to flow in smallquantities throughthe pipes, so that the material will be sprinkled asit is mixed. The stirring action is continued until the gas formed bythe introduction of water has been entirely eliminated, and then one ofthe 'empty molds is brought beneath the spout 18, and said spout isopened by withdrawing. V

pivoted the gate 19, the material being fed through said spout into themold by the plows or shovels 22. Simultaneously with this feeding actionthe mold is given a vertical shak-,

ing oi'jostlitifig movement by means of the actuating-bar 51, which iscontinuously swung in a vertical position and allowed to drop by meansof the wiper-cam 58, operating the bell-crank lever 56, which, .asalready described, is connected to the free end of the bar 51.; Thematerial will be thereby thortherein will be driven off and the surpluswater willalso be driven to the top, so that it will flow off, leavingapost that is smooth and thoroughly compact. When one mold is filled,the carrier is turned to bring another to position, and the action canthus be made practically continuous, the 'filled molds being removed andreplaced byempty ones.

[Itwill thus be seen that a comparatively simple machine is 1 lessconcrete or arti cial stone articles canbe manufactured with ease andrapidity andat "small cost, i

.From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be a parent tothose skilled in the art without ,rther description, and-it will beunderstood that various changes in the size, shape, proportion, andminor details -of construction may be resorted. to without'departingfrom the spirit'or sacrificing any of the advantages of the invention.
